Application filed April 13, 1914. Serial No. 831,546.

To all whom it may concern.

Be it known that I, JOHN H. KATE, a citizen of the United States, residing in Des Moines, county of Polk, and State of Iowa, have invented a new and useful Improvement in Water-Trays for Incubators, of which the following is a specification.

The object of this invention is to provide improved means in an incubator for containing water to supply moisture to the contents of said incubator during the process of incubation.

A further object of this invention is to provide an improved water tray adapted to be removably mounted in an incubator.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which Figure I is a plan illustrating my improved device mounted in position for use. Fig. II is a vertical section of the same. Fig. III is aperspective of the same In the drawings herewith a portion only of an incubator ofcommon type is shown, in which the numeral 10 designates generally a lamp chimney mounted in a cylindrical sup port 11 and surrounded by a guard or shield A bed or tray 13 covered with wire mesh surrounds the cylindrical support 11 and is adapted to receive eggs to be incubated. A cap or deflector 14 is mounted removably on the upper end of the lamp chimney 10 and is designed to spread and deflect heat from 7 said lamp chimney, and is also provided with tubes or pipes 15 adapted to lead some of the heat to different portions of the incubator.

The numeral 16 designates generally a wafer of common form adapted to be acted upon and expanded by the heat from the lamp chimney to the end of regulating and controlling the temperature of the interior of the incubator, through a lever 17 leading to and designed to operate devices (not shown) of common form adapted'to admit atmospheric air to the incubator.

My improvement consists of a tray or receptacle removably mounted on the cylindrical support 11 adjacent the lamp chim-- ney 10 and designed to contain water. This tray or receptacle preferably is of sheet.

metal and is generally circular in plan view. It is formed with a bottom 18 and an 111- tegral outerrim or side wall 19 rising from the outer margin thereof. The bottom 18 is formed with a central opening of circular form to receive the lamp chimney 10 and shield or guard 12, and said opening is surrounded in part by an inner rim or side wall 20 concentric with the outer wall 19. The

bottom 18 also is formed with an opening at one side and leading from the central opening to the circumference of said bottom, and supplied with radial side walls 21, 22 conmeeting the outer side wall 19 and inner side wall 20. This lateral opening in the bottom is for the purpose of receiving and permit: tingfree and unrestricted operation of the lever 17 and thermostat devices.

The tray or receptacle so described is f mounted loosely on the top of the cylindrical support 11, by removal of the cap or deflector 14, and is supplied with water. This water is evaporated by the heat of the lamp chimney 10 and moisture is supplied to the eggs under process of incubation, it being a well known fact that it is desirable to supply a certain amount of moisture during such process.

I claim as my invention 1. In an incubator having a cylindrical support, a lamp chimney disposed in the cylindrical support and extending thereabove, a water tray mounted on the cylindrical support and provided with an enlarged central opening, and a guard surrounding the chimney and extendingpartially within the central opening of the water tray.-

2. In an incubator having a cylindrical support, a lamp chimney disposed in the cylindrical support and extending thereabove, a water tray having a central opening removably receiving the lamp chimney, the latter extending above the tray, and a defiector removably supported on the extended portion of the chimney above'the water tra for spreading the heat thereover.

3. In an incubator having a cylindrical support and a lamp chimney therein and lamp chimney, a Water tray adaptedto be said bottom also being formed With a lateralopening to receive said thermostat lever, said lateralopening leading to the central 013611- ing, and side Walls for said lateral openin 1 and connectlng the inner and outer side Walls.
